Obama up in polls in Pa., Ohio and Fla.

Quinnipac has three new polls showing Barack Obama leading John McCain in the key states of Ohio, Pennsylvania and Florida. Obama leads by seven points in Pennsylvania and two points in Ohio and Florida.

This is a weaker performance for Obama than in June, but a better performance for him than in any month but June. Our model weights those two factors, and concludes that the status quo has more or less been preserved. As of last night, our model gave Barack Obama a 68.0 percent chance of winning the election in November. With these polls rolled in, he has a 67.7 percent chance.

There’s nothing really dramatic here, in other words. And to the extent there’s any news at all, it’s that Florida and Ohio continue to move toward one another in the polling, which has a lot of implications for resource allocation going forward.
